Hi and welcome to the group. You have a nice assortment of birds and animals. If I lived in the country I would have way to many pets I'm sure.
I think you solved your question in your later post. The red light now being white. Any little change will be noticed and loudly addressed by the squalking. That is my guess I think I would try and put something red over the bulb and see how that works. Good luck.
Thank you. Yes, I resonate with animals more than people, generally. I'm so happy to finally have my spot in the world, gee took long enough, but, I'm very thankful.
I have replaced the red filter every night since, and while they are a little quieter, they are still being noisy. I think it may be the combination of things like someone else is suggesting.
